Companhia de Saneamento Básico do Estado de São Paulo – SABESP files its 2025 Form 20-F, highlighting a transformative year marked by privatization and a new regional concession model.
The State of São Paulo completed SABESP’s privatization in July 2024 via a secondary offering of 220,470,000 common shares, cutting its stake from 50.26% to 18.00%. A golden-share preferred share grants the State veto rights over the company’s name, headquarters, corporate purpose and certain voting limits.
The URAE-1 Concession Agreement now governs 371 municipalities and advances universalization targets to 99% water and 90% sewage coverage by December 31, 2029, including rural and informal areas. SABESP estimates a R$70 billion capital expenditure program for 2024–2029 and invested R$15.2 billion in 2025.
The report details sizeable risk factors: exposure to Brazilian macroeconomic volatility, a Selic rate that peaked at 15.00% in 2025, foreign-currency debt of R$10.6 billion, legal proceedings totaling R$18.2 billion (with R$1.9 billion provisioned), regulatory uncertainty around tax and sanitation reforms, tariff and concession risks under URAE-1 (including Factor U and potential early termination), and sizable receivables from the State of São Paulo.
Cybersecurity and data protection remain key themes, with a 2024 cyberattack resolved without identified material harm but continued LGPD exposure. Management also reports material weaknesses in IT-related internal controls over financial reporting as of December 31, 2025, though no misstatements were identified, underscoring remediation as a priority.
Companhia de Saneamento Básico do Estado de São Paulo – SABESP approved a 5-for-1 stock split of all its common shares at an Extraordinary General Meeting. Each existing common share will now correspond to five common shares, with no change to total share capital.
After the split, the company’s capital is divided into 3,524,534,025 book-entry common shares without par value and one special class preferred share held by the State of São Paulo. Shares trade ex-split from April 29, 2026, based on holders of record on April 28, 2026. Split shares are credited on April 30, 2026 and reflected in shareholder positions at market opening on May 4, 2026, carrying the same dividend and distribution rights as before.
Sabesp plans a 1-for-5 stock split of its common shares, subject to approval at an Extraordinary Shareholders’ Meeting on April 28, 2026. Each existing common share will become five common shares without changing the total amount of the company’s share capital.
If approved, Sabesp’s Brazilian custodian will automatically credit the additional common shares to investors holding stock on B3, while Bank of New York Mellon will issue and distribute additional American Depositary Receipts to NYSE investors. The company states that proportional ownership and all economic and voting rights, including dividend entitlements, will remain unchanged after the split.
Companhia de Saneamento Básico do Estado de São Paulo – Sabesp and EMAE plan to study a possible share-based reorganization. Management of both companies will assess the feasibility of Sabesp incorporating all EMAE shares it does not already own, under Brazilian corporate law.

If ultimately approved by boards and shareholders, EMAE would become a wholly owned Sabesp subsidiary and EMAE shareholders would receive Sabesp shares. The goal is to simplify the corporate structure, consolidate shareholder bases into one company and reduce operating costs.
